Be used to allow the parameter of contextual access or standard to be based on some user-defined preferences.A preference is limited by user or communication device position.For example, constantly can relate to the user position.In other words, the user still is at work and depends on constantly, and this can be limited (for example, After Hours, having only the kinsfolk can access context information) by user's preference.Another preference is that the environment by user or communication facilities is limited.For example, can predict the visit to contextual information on mobile subscriber's existing context, mobile subscriber's existing context can be that any amount of position and the environment of comprising (for example, fixedly relatively moves, the relative office of car is family relatively, or the like) in interior thing.
Similarly, can limit visit according to Another Application program (for example, agenda).For example, standard can influence the Another Application program on (leverage) client, such as instant message client that can be used for this or agenda application program.In the example of instant message client, the user may wish to put up notice (for example, presence information) when he leaves.Instant message client can influence other contextual informations or make in conjunction with other contextual informations and be used for the granularity (granularity) of the information that increases or upgrade contextual information by the individual in its contact book or " good friend " tabulation.In the example of agenda, during work, the agenda that business application can calling party, and access context information.Another preference can comprise can access context information group or unique individual.Such preference may further be divided into the specific information request from group or unique individual.Similarly, preference can comprise can access context information various services or application program.Similarly, such preference may further be divided into the specific information request from service or application program.
In all above-mentioned examples, contextual information can be the part restriction.In other words, change granularity all contextual informations, not have such contextual information or the such contextual information of part be specific.This can comprise the format of contextual information (for example, audio frequency, vision, text) or present.For example, user's spouse can receive contextual information (such as the position on the map), and it demonstrates the user in office, and wherein business application can demonstrate the user just in particular conference room to user's the person in charge.As another example, the commercial enterprise of restriction tracking application program can only be in working time access context information.In addition, can so that the granularity of change in information can use.In the example of position, user's position can be specific, for example, the user onboard or the user in particular address.
Be used to allow the parameter of contextual access or standard to be scheduled to, so that to user transparent.Replacedly, access permission can obtain prompting and prepare whether to allow to send this information when each its context is requested.Alternatively, the user can protect access context information implement pin.Similarly, affirmation or token can be associated with access permission, and content-based own.For example, the individual of request user context information will obtain the prompting of password or PIN, if perhaps do not know password, can ask password.This can comprise that the user who separates mutually with contextual information confirms and/or key or token distribution automatically.At this moment, key or token can be managed to the context Control Server of individual's (person-to-person) application program by the individual.According to such method, can control token to context and verify, and token can be based on above-mentioned standard and the termination that expires.In addition, hash (hashing) algorithm that contextual information and key can distributions safe in utilization makes up, and can be checked by the people with key, thereby to its decoding.
In a preferred embodiment, be used to allow the parameter of contextual access or the standard can be based on right that the user proposed and permission and on the frequency of updating context, be restricted.For example, to the request of contextual access, can provide uploading of primary information sometime immediately or in future to content supplier, perhaps provide one group of cycle of contextual information to upgrade, indefinite number of times perhaps carries out preset times periodically or in variable future time.
Fig. 3 has shown the method for carrying out context information management according to the present invention, in portable communication device.First step 202 is included in contextual information is provided in the communication facilities, and it can be downloaded by content supplier.Content supplier can be restricted to individual, personal group, service or content supplier or the like.Next step 208 comprises the restrict access of dividing the pairing contextual information by content supplier or provider's request.Distribute and comprise the restrict access of shining upon qualification by the common request in provider's (that is, the title of provider or sign), the request of specific provider or the provider.Allocation step 208 can be used as one or more automatic operations and finishes, and also can be used as manually-operated and is finished by the user who points out when content supplier's request contexts information.Next step 218 comprises by from the request to contextual information of the restrict access filtering content provider of preceding step, thus the contextual information that the identification Licensing Content Provider is checked.Next step 220 comprises that the contextual information with the permission of identification sends to content supplier.This can also comprise and not send contextual information,, filters out all information that is, perhaps refuses 215 requests.Forwarding step can also be included in the constantly different of restrict access qualification and in the restrict access permission, send content supplier's information requested renewal.
Typically, after step 202 was provided, content supplier will ask 204 contextual informations from communication facilities.Can select to ignore this request, do not provide contextual information or confirm this request, provide contextual information.Usually, restrict access can be the user before request step 204 takes place for provider or request predetermined.Replacedly, restrict access can be set to default.Alternatively, if unqualified any restrict access 206, the user can obtain prompting and come assign access limitations 208 when the request of receiving from content supplier.At this moment, write rule 210, be defined for the restrict access of particular content provider or request.These rules are used for filtration step 218 after a while.Preferably, the restrict access in the allocation step 208 is time correlation.In other words, these rules can change automatically, and it depends on: the existing application of moving on the environment of communication device position, communication facilities, the communication facilities and the moment.Alternatively, the restrict access in the allocation step can comprise request or access to your password 216 by content supplier, with the contextual information in the accessing communication equipment.
In case the rule of defining and asking, the present invention is 212 requests and rule relatively.This comprises that request with provider's accessing communication device context information is mapped to any restrict access of the qualification that is applied to this content supplier, provider or request or request itself.If find the restrict access 214 that provider or request coupling limit in mapping process, method just filters 218 and send 220, and it is at all or part of contextual information of permission.But,, will refuse to ask 215 if in mapping process, do not find coupling.Replacedly, if do not find coupling, just can provide full detail 220 (supposing that if the user wishes to refuse all information transmission this will be restricted to restrict access or default in allocation step 208).
In a preferred embodiment, the present invention also comprises step: content supplier processes the contextual information of 222 contents to be fit to receive from communication facilities, and the load content after will processing then is in communication facilities.Information specific processing can be content-based the requestor and/or owner's preference.
